Coman, 18, became the youngest player to feature for PSG in Ligue 1 when he made his first-team debut in February 2013.

Though he made just a further two top-flight appearances under Laurent Blanc last season, the attacking midfielder was a regular participant in training sessions with the likes of Zlatan Ibrahimovic and Thiago Silva, and made his France under-21 debut last month.

The French champions had offered him a professional contract, but Coman rejected that in favour of a move to Turin, and told Corriere dello Sport he had had his pick of destinations, including the Gunners.

"Newcastle, Arsenal and Tottenham were interested in me," the teenager said. "But I chose to join Juventus because of their history. It was the club of Platini, Zidane and Trezeguet."
